3D Terra Plus (TEM-600) Transient Electromagnetic survey equipment

A 3D Terra Plus transient electromagnetic (TEM) survey, also known as a time-domain electromagnetics (TDEM) survey, is a geophysical technique that measures the electrical resistivity of the subsurface. TEM surveys are used in a variety of applications, including: Mineral exploration, Groundwater exploration, Environmental mapping, and UXO detection and characterization. 

TEM surveys are non-invasive and don't require direct contact with the ground, making them ideal for aerial or moving surveys. They can also be used at sites with resistive surface layers. 

Here's how a 3D Terra Plus TEM survey works: 

1. A transmitter loop sends an electric current into the ground

2. The current induces eddy currents in the conductive underground

3. The eddy currents produce a secondary magnetic field

4. The returning signal is measured as a function of time

5. The data is inverted to create a layered earth model of resistivity

The depth of investigation can range from tens to hundreds of meters below the land surface. Factors that affect the depth of investigation include: geoelectric subsurface properties, transmit or measurement time, and wire loop size.
